The RSM2800 magnetic encoder from Novotechnik (Southborough, MA) counts turns, measures angles exactly, and remembers shaft positions without power. The RSM2800 is based on Novotechnik’s patented non-contact multi-turn for absolute 5,760° (16 turns) measurement. The wear-free technology combines advanced capabilities with...

Galil Motion Control (Rocklin, CA) offers the DMC-300xx Pocket Motion Controller series single-axis Ethernet motion controller. It combines a high-performance motion controller and an 800-W sine drive in a low-cost, compact 3.9" x 5.0" x 1.5" package. The DMC-300xx is also available as a controller-only model...

The A3200 MotionPAC from Aerotech (Pittsburg, PA) is a software-based PLC that is integrated with Aerotech’s A3200 motion controller to increase programming efficiency and decrease development time. The MotionPAC can be used independently for full machine control or in conjunction with AeroBasic™ programs....

To advance the acceptance and incorporation of sustainable remediation metrics into the larger body of remedial work, the Center for Sustainable Groundwater and Soil Solutions (CSGSS) within the Savannah River National Laboratory (SNRL) created the Sustainable Remediation Initiative (SRI).

An acoustic energy-based probe has been developed that incorporates multiple acoustic sensing elements in order to obtain the acoustic pressure and threedimensional acoustic particle velocity. With these quantities, the user can obtain various energy-based quantities,...

Lightweight, electromagnetic interference (EMI) immune, fiber-optic, sensorbased structural health monitoring (SHM) will play an increasing role in aerospace structures ranging from aircraft wings to jet engine vanes. Fiber Bragg Grating (FBG) sensors for SHM...

A process was designed to fuse data from multiple sensors in order to make a more accurate estimation of the environment and overall health in an intelligent rocket test facility (IRTF), to provide reliable, high-confidence measurements for a variety of propulsion test articles.

Traditionally, nodes in a sensor network simply collect data and then pass it on to a centralized node that archives, distributes, and possibly analyzes the data. However, analysis at the individual nodes could enable faster detection of anomalies or other...

Any manned missions to extraterrestrial locations will require shelter structures for a variety of purposes ranging from habitat to biomass production. Such shelters need to be constructed in such a way as to minimize stowed volume and payload weight. The structures must also be very durable and have...

Five improvements are reported in cold-plate fabrication. This cold plate is part of a thermal control system designed to serve on space missions.

detect minute amounts of emitted electromagnetic energy. Calibration of these receivers is vital to the accuracy of the measurements. Traditional calibration techniques depend on calibration reference internal to the receivers as reference for the calibration of the observed...

A novel cognitive computing architecture is conceptualized for processing multiple channels of multi-modal sensory data streams simultaneously, and fusing the information in real time to generate intelligent reaction sequences. This unique architecture is capable of...

For the Lunar Reconnaissance Orbiter, the Command and Data Handling subsystem consisted of several electronic hardware assemblies that were connected with SpaceWire serial links. Electronic hardware would be commanded/controlled and telemetry data was obtained using the SpaceWire links. Prior...

An existing three-channel analog servo loop controller has been redesigned for piezoelectric-transducer-based (PZTbased) etalon control applications to a digital servo loop controller. This change offers several improvements over the previous analog controller, including software control over...
